Why they’re on the list: For helping artists sell 55 percent more stuff over last year

In its short history, Brooklyn-based Etsy has become the leading site for artists and craftsmen to sell their wares. Tapping into the tradition of local craft fairs (or the newer eBay approach), sellers set up their own personal storefronts where they can sell just about anything – including clothing, jewelry, and food products – for a flat fee of $0.20 an item. With vintage and handmade items always in demand, Etsy’s online marketplace has thrived, as thousands of sellers and even more buyers in 150 countries have resulted in an average of $30 million in goods sold a month (55 percent more than in 2009). Perhaps more importantly the company says it’s profitable and may consider an IPO in the coming year.
